The present invention relates to an unmanned mast for a tower crane comprising: a mast leaning prevention unit to prevent a vertical beam from being distorted by being installed in the vertical beams of a mast, and preventing the mast from leaning to one side by preventing a shoe installed in the vertical beam from leaning. The mast leaning prevention unit comprises: a fixated surface installed in both sides and fixated to a corresponding surface of the vertical beam; a pair of slip inducing surfaces enabling a shoe support bracket formed and mounted on an upper and a lower side to lean to a center of the mast leaning prevention unit; and a moving surface formed between a slip inducing surface, and supporting the shoe support bracket. As such, the fixated surface of the mast leaning prevention unit is fixated to a corresponding surface of the vertical beam and supports two surfaces of the vertical beam in an H-beam shape, thereby preventing the vertical beam from being distorted. Moreover, the shoe support bracket is always located on the moving surface of the mast leaning prevention unit by the slip including surface even if the shoe leans to one side as the upper part of the shoe support bracket is located on the upper surface of the mast leaning prevention unit; thus preventing the shoe from leaning to one side of the mast by the mast leaning prevention unit, and such that an unreasonable deflection load is not applied to the mast, preventing the tower crane from being turned over.

    본 발명은 무인 타워크레인용 마스트에 관한 것으로, 마스트의 수직빔들에 설치되어서 수직빔의 뒤틀림을 방지시키고 수직빔에 설치되는 슈의 쏠림을 방지하여서 마스트가 일측으로 쏠리는 것을 방지시키는 마스트쏠림방지부가 구비되며, 이 마스트쏠림방지부는, 양측에 형성되어서 수직빔의 대응면에 고정되는 고정면과, 상하측에 형성되고 안착된 슈지지브라켓이 마스트쏠림방지부의 중앙측으로 쏠리도록 하는 한쌍의 슬립유도면과, 한쌍의 슬립유도면 사이에 형성되어서 슈지지브라켓이 지지되는 유동면으로 이루어진다. 따라서, 마스트쏠림방지부의 고정면이 수직빔의 대응면에 고정되어서 H빔 형태의 수직빔 두면을 지지하므로 수직빔이 뒤틀리는 것을 방지한다. 또한, 슈지지브라켓의 상단부가 마스트쏠림방지부의 상부면에 안착되면 슈가 일측으로 쏠려도 슬립유도면에 의해 슈지지브라켓은 항상 마스트쏠림방지부의 유동면 위에 위치된다. 따라서, 슈가 마스트쏠림방지부에 의해 마스트 일측으로 쏠리지 않게 되므로 마스트에 무리한 휨하중이 작용하지 않으며, 이에 따라 타워크레인의 전복이 방지된다.
